When it comes to silicone rubber products, most people should be familiar with them. For instance, the common silicone protective covers, the rubber tires used in cars, the sealing strips at door edges, and so on, all these products need to be molded through molds. The quality of the molds directly determines the quality of the products. So, what issues should we pay attention to before opening the molds? Yongyong Silicone Rubber, with 23 years of production and manufacturing experience, will come and help us review these issues together today.
Firstly, silicone rubber molds can be roughly classified into three types based on the different molding methods: flat molds, transfer injection molds, and injection molds. Among these, the most common type is the flat mold. Currently, the popular silicone products on the market also include liquid injection molds, etc. The specific type that is most suitable needs to be determined based on the product structure, appearance requirements, etc.
1. Based on the product structure, appearance and size requirements, the mold forming method is determined.
2. Analyze the product structure and determine the demolding method of the product. This is of great significance as it directly affects whether the subsequent mass-produced products will be successful.
Successful demolding, the labor intensity and production efficiency of the production personnel.
3. Based on the customer's order quantity and the machine tonnage, determine the mold size and the number of cavities.
4. Determine the parting surface of the mold. This is also of great significance as it will directly affect the processing efficiency and difficulty of the mold, as well as the appearance of the product, such as whether there should be a parting line on the product's surface.
5. Based on the customer's requirements for product quality and price, the appropriate mold steel should be selected, which will have a significant impact on the processing of the mold and its service life.
6. The shrinkage rate of the mold should be determined based on the material and hardness requirements of the product. This will determine whether the produced product can meet the size specifications.
